Repair of toilet drain fittings with your own hands

In detail: repair of toilet flush fittings with your own hands from a real master for the site my.housecope.com.

The most common problem in bathrooms is a faulty toilet cistern. Sinking buttons, slow filling of the storage tank, incessant water leakage from an overfilled tank. All kinds of malfunctions do not happen. These situations can arise for a variety of reasons. To reveal the true cause in each individual case, it is necessary to dismantle the cover. After determining the nature of the malfunction, you can perform a simple repair of the toilet cistern with a button with your own hands, without resorting to the help of plumbers.

We unscrew the drain button by hand, rotating it counterclockwise. No tools are required for this operation. We take out the button and carefully remove the cover.

Inside the drain tank there are two mechanisms, in the details of which there may be a malfunction that causes a leak:

drain mechanism;
a shut-off valve responsible for the flow of water from the water supply into the container.

We carefully examine the drainage mechanism, assessing the height of the water level. If the water is in the overflow area, then this indicates that it does not hold the locking device.

The water in it is above the float, and therefore reaches the drain channel, through which it is drained into the sewage system.

If the water level is at the adjusted height in the shut-off device, then the leakage is caused by a malfunction of the valve in the drain mechanism. There are two main reasons for this.

Water flows above the overflow device, which means that the drain valve is in working order, and the problem lies in the locking mechanism. We make a drain, freeing the container from water. We close the water supply valve to the system. We remove the drain mechanism device by turning it slightly counterclockwise. We take out the removed part from the container, inspect the condition of the sealing rubber ring, which is the shut-off valve of the drain mechanism. We are convinced of its integrity. We put it aside.

If this is not the case, then remove the ring and rearrange it with the reverse side, thereby ensuring a tight fit of the rubber to the surface of the bottom of the container. You can immediately install a new O-ring purchased from a plumbing store.

The second problem: the formation of plaque, the accumulation of mucus on the surface of the shut-off valve, which violates the tightness of this system. You can eliminate it by cleaning the part from layers. Rearranging the ring is very simple. Remove the plastic lock washer. Take the rubber part, rinse it thoroughly, then turn it upside down and press it with a washer installed in its original place.

We turn off the water supply system and the locking mechanism. There are tanks with lower water supply and from the upper one, located in the side wall of the tank. The inlet hose is connected and the valve is at the top. The type of connection does not play an important role, since the malfunction is directly related to the state of the shut-off valve. Grains of sand, rust from the water supply system can get under the valve, which violates the tightness of the locking ring.

In addition, the valve itself can be deformed during long-term operation. A manifestation of this is a specific recess formed on the sealing gum. A part with such damage can no longer restrain the flow of water from the water supply system.

Let's remove the mechanism that controls the water supply to the container. To do this, unscrew the large nut by turning it counterclockwise.
We take out the removed device from the tank, temporarily putting it aside.
Consider a membrane that serves to reduce the pressure of the water coming from the system.
We rinse the sealing ring taken out with the membrane from the inlet pipe.
Next, we proceed to disassemble the shut-off valve body, which was put aside for a while.
First of all, we snap off the float and remove it.
Then we remove the body of the float itself, moving the tongue that fixes the position of the part in the tank to the side.
Then we disassemble the valve installation site. To do this, take a screwdriver, pick it up on both sides, pulling out the valve with a "pull" movement.
We examine the socket from which the valve was pulled out, and we see a small hole, which it should close tightly when the tank is full of water.
The deformed valve looks like a miniature rubber band, in the center of which a recess is squeezed out, the size corresponding to the size of the hole letting water into the tank.
During the first repair, this elastic-flap is turned over with the other side, which is smooth and even.
When repaired again, this gum-valve is cut with a sharp clerical knife strictly in the middle. First, the first deformed part is placed in the socket, and then the second - with the smooth cut side up. Thus, one valve can be used three times, each time turning the parts with an even surface towards the hole through which the tank is filled with water.
You can reinforce the valve with an additional piece cut from dense foam.
We put the valve back into place in the socket, securing it by pressing it until it snaps into place.
We assemble all the parts in reverse order: body, float, installation on a branch pipe, fixing the device with a swivel nut.
The valve, when raised, should extend the float 1 cm above the body in which it is located. It is in this position that it is necessary to fix the position of the float by snapping the locking mechanism.
We install in place the second part that closes the drain hole in the tank. With a sharp clockwise movement, we fix it in place. A characteristic click should sound.

We open the tap and start the water supply system. We follow the process of filling the tank, paying attention to the moment of the shut-off valve actuation, which has been repaired. As soon as the water poured into the body of the float and raised it by 1 cm, the water supply to the tank stopped. We put the cover in place, and fix it with the water release button, twisting it along the thread of the drain device part until it stops in the clockwise direction. We look at the result of the repair work. There is no uncontrolled flow of water from the cistern in the toilet. The water meter has measured, confirming that there is no water intake from the system. We will make a control drain to once again be sure of a positive result of the repair. The problem was fixed by hand. Money is saved by eliminating the need to purchase a new drainage mechanism and shut-off valve.

You can learn more about repairing the flush mechanism of a toilet cistern with a button in the video.

If, during flushing, streams of water appear from under the tank, then this indicates a depressurization of the drain hole. A gasket is responsible for the tightness of the connection of parts of the entire structure, which can be round or of another shape, depending on the model. The situation with water flow can only be corrected by replacing the seal. Before going to the store, you need to remove the drain tank and get the sealing gum. It is better to show the removed part to sellers who will help you choose a good replacement for it.

Sometimes it is better not to buy exactly the same seal, as it will fail again after a while. Manufacturers produce consumable parts from the latest materials, the quality of which is superior to previous products. It is these rubber bands that are worth taking.Having installed the purchased consumable in place of the old gasket, the tank is installed in the reverse order. Above, we have already talked about how to install the flush mechanism and the inlet valve, as well as how to fix the tank on the toilet bowl.

The low rate of water entering the toilet tank is associated with clogged filters. We carry out repair work in the following order:

by turning the tap handle, we shut off the water entering the toilet from the cold water supply system;
we unscrew the flexible connection from the valve supplying water to the toilet, located either from the bottom or from the side, depending on the model of the sanitary ware;
in the clogged hose, we remove the blockage and check the water pressure in the water supply system by lowering the end of the flexible hose into the toilet, if its length is enough;
otherwise, we use a five-liter plastic bottle or canister to drain the water;
turn on the tap, if the pressure is good, then we start cleaning the water supply valve from accumulated debris;
this part is not available in all toilet bowls, but if it is, it needs cleaning;
we take out the filter from the valve using pliers, grabbing the part by a small pin;
we wash the extracted grate in the sink under a stream of clean water from clogged solid particles and from accumulated mucus;
then we put the washed filter in place, turn on the water and see if the problem is fixed or not.

If the problem is not resolved after flushing the filter and flexible hose, then we flush the entire water supply valve by taking it out of the tank, after removing the toilet lid.

After all the steps described, the problem is usually resolved. The algorithm for repairing the toilet cistern with a button in the case of slow filling with water is clearly shown in the video.

In the old toilet cistern, we are dismantling the old fittings that have become unusable, and we are installing a new water supply and drainage system. We purchase universal fittings that fit all toilet cisterns. For economical use of water, we buy a two-button drainage mechanism that allows you to change the drainage volume depending on the type of washed off human waste.In such fittings, the manufacturer uses:

two-mode push-button mechanism;

manual adjustment of the volume of small and large drainage of water;

a rack of the drain mechanism adjustable for the height of the tank;

changing the thrust by reinstalling the lever in one of the existing holes;

clamping nut with rubber gasket;

a valve that closes the drain hole in the toilet bowl.

We will replace the old fittings. To do this, unscrew the button holding the toilet lid and pull it out of the socket. Remove the cover. Let's cut off the water supply to the tank. Disconnect the flexible hose. Loosen the screws holding the cistern to the toilet bowl. Remove the tank and place it on the reclining seat cover. Remove the rubber gasket and then unscrew the plastic clamping nut by hand. Then we remove the old drain mechanism.Next, we put a new drainage mechanism, after removing the rubber seal from it and unscrewing the clamping fastening nut. After installing the drain mechanism in the hole in the tank, fix its position with the removed parts. When installing the cistern on the toilet, do not forget about the O-ring placed over the plastic nut. Then we insert the pins of the tank into special holes in the bowl, screwing the wing nuts onto them from below. We tighten the fasteners evenly on both sides, avoiding skewing of the part to be installed. If necessary, we replace the fasteners with new parts with gaskets.When connecting the water supply hose to the side inlet valve, hold the part inside the tank from twisting. We tighten the nut with a special wrench or pliers. Install the tank lid, tighten the button. If necessary, adjust the stand, move the lever.The two-button button has two pins, with the help of which the desired drainage mechanism is activated. The length of the pins reaches 10 cm. They are shortened to the required length, depending on the height of the tank. Screw into the button. Insert into the lid and fix the position of the button with a nut from the inside. Place the lid on the tank. Turn on the water supply. Press a small part of the button, about 2 liters of water are drained. Press most of the button, about six liters of water are drained.

The toilet bowl in every home is an element of everyday life, without which it is simply impossible to do. It is used much more often than all other plumbing fixtures. That is why it fails more often than other devices. And its most vulnerable component is the tank, which consists of several internal components. Their mechanical damage, as well as careless handling of the tank are the reasons for this device to lose its performance. In this article, we will look at how to repair a toilet cistern with a button on your own, without calling a team of plumbers.

All cisterns have a similar design. The only difference is in the mechanism for starting the water.

Structurally, a toilet cistern with a button or two buttons, as well as a drain lever, can be represented as a set of interacting units:

Filling valve... He is responsible for maintaining the water level at a certain level. The valve is controlled by a hollow float. When the water rises to the desired level, the float closes the water supply channel to the tank;
Plastic float fixed to the filling valve. Works on the principle of a rocker, rising when filling the tank;
Drain valvehaving an overflow system. Modern variants of the tanks involve the control of this valve by pressing a button. When manually controlling the drain of the old model, it is enough to pull the lever or chain to start the water into the toilet;
Overflow is an obligatory component of the tank. It is height adjustable so that the water level is set to a limit. When this level is exceeded, water flows through the overflow pipe into the sewer without pouring out through its walls.

The main structural elements and the principle of operation of the mechanism are the same for all types of cisterns, only their implementation differs

A mechanically drained cistern is very simple to operate. Water enters it through the filling valve when the float is in the lowered position. After reaching a strictly defined level, the float shuts off the water supply. The drain is controlled manually.If the tank is equipped with buttons, then the water is drained after pressing them. In this case, the drain valve opens partially or completely, allowing water to flow into the toilet. The float is lowered to open the filling valve.

The structure of the toilet cistern with two buttons is a little more complicated, but you can use such a cistern more economically. If you press one of the buttons, the water is partially drained. Full drainage occurs when the second button is pressed.

Increasingly, you can find new types of tanks that have bottom water connection... It is advisable to install them if the use of the side connection is impossible due to lack of space. The main difference between such a tank is the presence of a diaphragm valve... Under the action of the pressure of water in the pipeline, the valve opens slightly and allows water to pass inside. When the water rises, the float presses on the piston rod, which gradually closes the diaphragm valve. When the set level is reached, the valve closes completely.

Fittings with bottom water supply and push-button control

Drainage malfunctions may well lead to the loss of the toilet bowl of its performance. For many, such a sudden breakdown can be a real natural disaster. In addition, no one will like the increased water consumption.

Read about what a hygienic shower for a toilet bowl with a mixer is and what types it is in a separate article.

And how to choose a pump to increase water pressure and in what situations it is needed, we described in another article on the site.

What kind of breakdowns are typical for cisterns? Let's list them in order of frequency of occurrence:

1. Water leaking from the toilet to the floor... Most often, water flows through an O-ring located between the bottom of the cistern and the toilet shelf. If the ring is cracked or warped, water will seep through it. Also, the place of leakage may be the gaskets of the fastening bolts with which the tank is attached to the shelf. They will have to be replaced if tightening the bolts fails. It doesn't matter if the old-style toilet cistern is being repaired or a modern system is being repaired. After all, they all have the same fasteners.

A high-quality sealing ring of the drain tank is the key to its good sealing.

Tip: When replacing gaskets and seals, it is recommended to lubricate them with liquid silicone to extend their life and prevent cracking.

2. There is a constant flow of water in the toilet... Most often this is due to an overflow of the tank, in which water flows out through the overflow tube. This can happen due to a change in the overflow height, a loose fit of the float to the shut-off valve, and the loss of its tightness by the float. The rubber seal on the drain fitting may also be worn out. Most often, the malfunction can be eliminated by adjustment. When the locking gasket is worn out, it is advisable to replace the entire drain mechanism.

3. Starting mechanism malfunctions... If you are using a push-button water supply mechanism, when you press the button, water may not flow into the drain. You will be able to repair the drain tank fittings with your own hands, since, most often, the lever mechanism that connects the button with the drain breaks. This also applies to tanks with a handle or chain.

4. Noisy filling of the tank... This happens due to the disconnection of the tube through which water is poured into the tank. This is typical for cisterns where water is supplied from the side. When the tube has fallen off, the noise of the incoming water will be clearly audible. To fix the problem, remove the top cover and install the tube on the fitting.

5. Water does not enter the tank... Repairing a toilet cistern with a button or with other flush mechanisms in the event of such a problem comes down to checking the inlet to the cistern.It is necessary to remove the valve from the tank and clean the inlet with a thin steel wire and rinse it with water.

Many people who are accustomed to old-style cisterns do not know how to fix a toilet cistern with a button. In fact, the differences between these systems are very minor. For many, the main problem is disassembling such a tank. Indeed, the button located on the tank lid requires careful handling during disassembly. But the device is very simple to understand.

To adjust the float, just raise or lower it slightly

Before buying a water filter, we recommend that you read our tips for choosing them.

The tank with bottom water connection uses a diaphragm-type filling valve. This can cause problem with filling the tank with low pressure in the water supply system... The water pressure may not be sufficient to depress the valve and fill the tank. If your system constantly maintains a low pressure, then it is better to replace the diaphragm valve with a rod analogue.

Another common problem is water leakage at the inlet to the supply valve reservoir. Its location is such that the valve is constantly under water. In case of insufficient tightness of the joints, the presence of leaks is practically guaranteed.

Repair of the toilet cistern with a bottom water supply is carried out after shutting off the water supply and removing the cistern lid.After that, the problem is eliminated according to the same algorithms that are described for repairing models with buttons.

We have figured out how to repair a flush cistern with a button, with two buttons or with a mechanical control. They differ slightly, mainly in the design of the control mechanism. The general principle of operation and repair is the same for all considered devices.

The video shows the do-it-yourself repair of the toilet cistern, or rather, the process of replacing its fittings.

A breakdown of the cistern is a problem that everyone has encountered. The first thing we do when we find this trouble is call the plumber. This is the right decision if you don't know anything about plumbing and you don't have any tools in the house. But if your hands are growing out of the right place, and there is a wrench in the closet, then why not try to repair the cistern yourself? After all, by doing repairs yourself, you save money and improve your skills.
How is the drain tank arranged, what kind of breakdowns does it have, and most importantly, to repair it? You will find the answers to these questions in our article.Before proceeding with the active steps, you need to study a little theory and understand how the toilet is drained. Any model has two main parts: a bowl that stands on the floor or fixed to the wall, and a water tank on top. This container is called the "flush tank".The principle of a water seal is at the heart of the water drain. When you press the lever (button), the plug opens, and the water is flushed out into the riser under the action of gravity.If you remove the lid on the tank, you will find a mechanism for draining the water. It consists of a float, a seal and levers. It is conditionally possible to divide the flush tank mechanism into two parts: the water intake system and the flush mechanism.

When the button is released, the drain hole closes and water begins to draw. The float controls its level and closes the tap at the right time.

Of course, depending on the manufacturer, the design is slightly different, but the meaning remains the same.

The principle of operation of the filling fittings is simple: when the tank becomes empty, it starts supplying water, when it is full, it stops. A float is required to determine the water level. If little or vice versa, a lot of water is collected, you can adjust the desired level yourself. It is recommended to use a volume of 5-7 liters of water.
The fittings that regulate the water supply can be of several types.

With lateral water supply (fittings are located at the top). Basically, such a water supply to the tank can be found in Russian-made toilets. The mechanism is cheap but very noisy. On more expensive models, to reduce noise, a tube is attached that supplies water to the bottom. Cistern: side feed mechanism device
With bottom water supply. This type can be found both on foreign models of toilet bowls, and on domestic ones. Thanks to the mechanism, noise from water is minimized.

Push-button drain mechanism
The drain mechanism is started either by pressing a button or by pulling out the stem. The most popular is the push-button version with a lever, which is shown in the photo. In toilets with a hidden cistern, the button is located on the wall. Therefore, repairing a hanging toilet is less convenient: all actions are carried out after removing the button through a small hole. The video shows the process of dismantling fittings from a built-in tank (installation).

The push-button mechanism can be one- and two-mode. The two-mode drain has two buttons: one drains the water completely, and the second half. This saves water when needed. Also, a similar mechanism can be implemented with one button, when the drain depends on the degree of pressing.
Image - DIY toilet drain fittings repair

First of all, let's examine the internal mechanism for defects. To do this, remove the top cover, usually it is fixed with a drain button. You either just need to unscrew it, or pull out the button and unscrew the fastening screw.

Before repairing the drain tank, be sure to shut off the water supply.

After you open the lid, you will see several holes with a diameter of 1.5-2 cm for water supply (maybe only one). In one of them, a filling fitting with a diaphragm valve will be fixed.

The membrane is very sensitive to the quality of the water, therefore its service life depends on the water filters. If there are no filters at all, then it is better to replace the mechanism with a Russian one with a stem valve.

Most often, the issue of repairing the toilet cistern can be solved by completely replacing parts. For expensive toilets, it is not difficult to find a repair kit with a sleeve and a membrane. It is more profitable to buy new fittings on cheap models, they are not very expensive. The main thing is to choose the required pipe diameter when purchasing, usually they are 10, 15 mm, as well as 1/3 and ½ inch.

Set of fittings for toilet repair

When replacing, you need to make a sealed joint, therefore, put on a sealing gasket before fastening. The fittings are tightened to the reservoir with a nut. Twist them slightly, otherwise cracks may appear.

Decorative plugs are inserted into the remaining free holes. If necessary, you can change the position of the water supply. If the plug is simply inserted into the hole until it clicks, and does not hold onto the nut, then no seals are provided in it, so water will flow out in the event of a malfunction.

At the bottom of the cistern there are holes for attaching to the toilet. Fastening takes place on metal or plastic bolts. Brass and stainless steel bolts are best suited for attaching the toilet. Of course, ordinary metal fasteners are stronger than plastic ones, but they quickly rust. Washers and rubber gaskets must be worn before fastening.

In the center is the largest hole for water drainage. The shut-off valve for the cistern is secured with a cap washer through a gasket.

The most common failure is continuous filling and water leakage from the container. This is due to the following factors:

float skew;
the float mechanism does not work;
Loose stop valve, old rubber seal.

The easiest way to solve the first problem, because in this case, the toilet does not even need to repair the cistern - just open the lid and fix the float. Also, sometimes the shut-off valve does not fit into place; it is also enough to simply put it manually into the recess.

The next problem is manifested in the fact that the water fills the tank to the limit and does not stop. To check the mechanism, lift the float up until it stops. If the water does not stop, then the float mechanism will need to be replaced.

And the last point is the old seal. It is very simple to determine such a breakdown: you just need to press the valve with your hand. If the water stops, you will have to replace the seal. It is also sometimes associated with too little weight of the locking mechanism. In this case, weights are added inside to make it heavier.

Another frequent breakdown is associated with a worn float. Its tightness is broken, and it does not float well, so the water in the tank does not rise to the desired level. You will need to replace the drain tank fittings, but you can also fix the float yourself. To do this, its hole is sealed with a sealant, glue, heated plastic or any other material at hand. You can also look into a plumbing store, perhaps there will be an analogue of this float.

Not very often, but such breakdowns happen to the tank as: leakage of the tank fixing bolts and failure of the water supply valve. To eliminate them, it is enough to change the gaskets and buy a new valve.

Since residents use the toilet every day, the flush device may fail. But if this happened to your toilet and you do not know how to change the drain mechanism in the toilet cistern, then let's consider possible options for replacing or repairing the water drain device. Image - DIY toilet drain fittings repair

First, let's look at the device of the drain fittings in the toilet cistern, which you will definitely have to familiarize yourself with when it comes to replacing or repairing it. To get to the mechanism itself, you need to remove the lid from the tank. It can be attached in different ways, so we are not in a hurry, but carefully examine the elements that can fix it. This is often a single nut located under the drain button.

Removing the lid is only the first step towards solving the question of how to change the drain mechanism in the toilet cistern.

Having removed the cover, you will have access to the mechanisms responsible for draining the collected water. I advise you to do everything carefully so that after your intervention the device works well again.

Toilet flush fittings consist of three main parts:

- a drain mechanism with a button,

- the body on which the mechanism is installed,

- a plastic nut for attaching the body to the bottom of the tank.

Before changing the flush mechanism in the toilet cistern, it will be useful to familiarize yourself with the principle of its operation. The toilet flush device functions thanks to a system of levers and rods, which, when you press the flush button, raise the shut-off valve of the mechanism and release water into the toilet.

There are two most common tank flush valve systems. This is a simple one, designed to release all the water once, and the other has a more complex system that allows a small amount of water to be released when needed. This is done for the sake of economy. The second option, although more complicated, has one advantage - it uses water sparingly.

The drain mechanism in modern toilets is made of plastic, only the valve has a rubber element. This is not strange, because they are designed to cut off the water. It is these rubber parts that can deform or collapse over time, which will lead to water leakage, or some particle will get under the rubber band, which will also cause the drain system to malfunction. Before changing the flush mechanism in the toilet cistern, it is imperative to carefully inspect it. If the mechanism is not damaged and when all working elements are cleaned it functions again, it is not worth changing it.But when the mechanism cannot be restored due to damage to the valve or breakage of a plastic part of the device, which is no longer in production, then the entire assembly will need to be replaced.

The main reason for replacing the drain mechanism is the duration of use. That is, the mechanism is outdated and beyond repair. The service life is influenced by water and the activity of using the drain system.

To replace the drain mechanism, you need to remove the cover and see how it is attached. You must first turn off the water, otherwise it will flow non-stop into the tank.

In the next step, try unfastening the mechanism, which in most cases is secured by snapping the mechanism onto the plastic barrel. This is done to simplify maintenance of the structure. The drain mechanism is unfastened by rotating it counterclockwise. When you manage to remove the mechanism, you can examine and repair it, if possible, but it is better not to skimp, because this device is inexpensive. Therefore, take the seized device as a sample and follow the store to purchase a new one. Having found an identical drainage mechanism, adjust it in the same way as before and reinstall it.

Now you have an idea of how to change the flush mechanism in the toilet cistern, but what if you can't get the exact same flush mechanism? Then you will have to install a drain device of a different design, and for this you will most likely need to dismantle the toilet cistern.

If you have not yet been able to resolve the issue of how to change the drain mechanism in the toilet cistern due to the difficulty of dismantling it, then you will need to remove the cistern. In this case, it is necessary to block the access of water to the toilet, disconnect the inlet valve or float from the water supply. Next, find the fixing screws and unscrew them. Now you can remove the tank and replace the drain mechanism.

Free selection of a qualified plumber in your city!

To do this, dismantle the body of the old drain device. Then, inserting the body of the new mechanism inside the tank, secure it with a plastic nut. Do not forget to install a gasket between the body and the tank.

Moreover, I recommend to coat the gasket on both sides with sanitary sealant. This will give you a reliable connection.

The next step is to install the cistern on the toilet. For this, we will also use a sealant treated gasket. Having installed the cistern on the toilet, we evenly pull it in with the screws. It is more convenient to tighten the fastening screws with a pipe wrench.

After completing the installation of the tank, we adjust the drain mechanism and fix it on the device body. Now it remains to connect the inlet valve, cover the tank with a lid and put the drain button.

As you can see, everything is not so difficult, the main thing is not to rush, understand the design and its features. Since the manufacturers of toilet bowls are different, accordingly, the configurations of mechanisms for draining water differ.

I hope, dear readers, the article site helped you figure out how to change the flush mechanism in the toilet cistern and, if necessary, you can do it without assistance. Read also:
